Marcs Updater

2021-03-28: This website is finally back online after roughly 3 months of downtime due to an infrastructure move. I am sorry for the inconvenience this may have caused!

There have been some reports about issues with the Updater not updating anymore. Please try the latest beta version and switch to another IP Check provider instead of the previous default dnsomatic.com. For some reason they are rate-limiting the number of requests to their service. The new IP Check provider selection allows you to choose another provider in such cases. You can test the functionality with the new "Test" panel.

Hi Marc, and thanks for this! A few days ago (5/15/2021), the updater provided by OpenDNS stopped working on my win-10 PRO (v1909) 64 bit machine. Support requests to OpenDNS simply go unanswered, but your updater (build 305 2017-04-23 PB 560 x64) seems to work! (At least it reports working, and unlike the one OpenDNS provides, it IS able to see and report my IP address). Anyway, should I inset a shortcut to this program into my STARTUP folder? Or maybe install it as a service somehow?

Dear Marc,

First of all, i wish you a happy/healthy new year!
I would like to know, what's the plan, when will you release 2.0? If i understand fine, the "custom provider support" is mean, if i have own dyndns solution with dyndns2 protocol, Marcs Updater client is works with my own server?

I have someone using a web filter which routes traffic through a proxy, so the HTTP/HTTPS IPs show up as the proxy server IP address, but I need to have the updater use the real IP address, which does show up on the Test tab under "DNS A IP (IPv4)".

Is there any way to add an option/dropdown to have it use/send that DNS IP update address for the hostname, instead of using the HTTP/HTTPS IP address?

Thanks a lot!

Marcs Updater is not working on Windows 7 Service Pack 1, it simply does not answer any, no error message and does not update the IP. Can someone help me?

Since a week or two Marcs Updater isn't working any more on either Win7 x64 and Win 10.
Doesn't update at all with DynDNS... Very strange... Is this due to a Windows update? :-(

Hi Marc! Can you explain how the filter tabs work? I am hoping to have the updater ignore VPN connections if possible. Thanks!

Hi! Where's the configuration located? I'm trying to remove the hostname and leave it blank, but the change won't stay unless I use a different hostname. Leaving it empty does not stay.
